| 在综合国内外相关研究文献的基础上，分析了浑水入渗机制和浑水入渗模型方面的研究进展。从研究成果中可以得出：利用静水做浑水灌溉入渗试验的较多，而利用动水做浑水灌溉入渗试验研究的比较少；不同含沙率对土壤入渗的影响研究方面研究成果比较多，而对不同的泥沙粒度组成对土壤入渗的影响研究较少；一次浑水灌溉土壤入渗研究较多，而致密层形成后进行二次灌溉情况下的土壤入渗研究较少；在室内利用下渗环等试验设备进行土壤入渗试验的较多，而在大田实验土壤入渗试验方面的研究较少；在裸地做土壤入渗试验的较多，而在有种植作物的大田上进行土壤入渗试验的较少。为了更深入的进行浑水灌溉下的土壤入渗机制的研究，建议以后试验中考虑浑水灌溉中动水入渗试验方面的研究，并将不同泥沙粒度组成对土壤入渗的影响、大田作物的影响、多次浑水灌溉对土壤入渗的影响以及浑水灌溉条件下水肥耦合方面的试验研究和浑水膜孔灌溉方面的试验研究等作为研究的重点，逐步深入的研究浑水灌溉入渗特性，为实际应用提供理论依据。 |

| In this article, on the basis of the comprehension on domestic and foreign literatures relevant to this research, progress of muddy water infiltration mechanism and muddy water infiltration model were analyzed. It could be concluded that a big portion of the experiments were accomplished using static water for muddy water irrigation infiltration test, and a relative small portion was done using dynamic water to do so. More achievements were obtained by studying the influence of different sand content on soil infiltration than by investigating the influence of different sediment grain size on soil infiltration. More studies on muddy water irrigation soil infiltration than on a second irrigation over soil infiltration after a dense layer was formed. Indoors utilization of equipment such as infiltration ring on soil infiltration was more than field test. Infiltration experiments in bare land were more than those in field soil with growing crops. To gain insightful understanding on soil infiltration mechanism of muddy water irrigation, it is advised that dynamic water may be involved in muddy water irrigation infiltration test. The influences of different sediment grain size composition, field crops, many muddy water irrigations, and water/fertilizer coupling under muddy water irrigation may need to take into experimental consideration. Muddy water in film hole irrigation experimental study should become the focus, gradually allowing in-depth research on characteristics of muddy irrigation water infiltration, and providing a theoretical basis for practical application. |
